Abstract: This contribution presents the outcome of applied Computational Fluid Dynamics for analysis of combustion technologies to find an efficient firing mode for use of bio and low calorific gaseous fuels in micro gas turbine combustors. The combustion technologies considered are based on the new concepts of Flameless Oxidation and Continued Staged Air. To optimise these concepts to burn low calorific gaseous fuels manifold numerical simulations were carried out using the CFD code FLUENT. The results achieved showed the influence of the fuel compositions on the flow behaviour inside the combustion chamber, reaction zone, flame structure and pollutant emissions.

Keywords: CFD modelling; lean calorific gases; micro gas turbines; burner systems; computational fluid dynamics; biomass combustion.
